BACKGROUND The Center for Epidemiologic Studies Depression (CES-D) scale is one of the most widely used tools to measure depressive symptoms in epidemiological studies. Given the importance of cross-racial measurement equivalence of the CES-D scale for research, we performed confirmatory factor analysis (CFA) of the 12-item CES-D in a nationally representative sample of Black and White adults i...

In recent years, emotional intelligence and emotional intelligence measures have been used in a plethora of countries and cultures. This is also the case for the Wong and Law Emotional Intelligence Scale (WLEIS), highlighting the importance of examining whether the WLEIS is invariant across regions other than the Far Eastern region (China) where it was originally developed. This study investiga...

This study investigated the factor structure and measurement invariance of the Mroczek and Kolarz’s scales of positive and negative affect in Iran (N = 2,391) and the USA (N = 2,154), and across gender groups. The two-factor model of affect was supported across the groups. The results of measurement invariance testing confirmed full metric and partial scalar invariance of the scales across cult...

In a cross-cultural study, it is crucial to understand whether items and the factorial structure of a survey instrument are equivalent across different cultural groups, because items might mean differently to different population groups, and thus the factorial structure of the measurement instrument might not hold across groups. The purpose of this study was to investigate the measurement invar...

The Patient Health Questionnaire (PHQ-9) is a widely-used screening tool for depression in primary care settings. The purpose of the present study is to identify the factor structure of the PHQ-9 and to examine the measurement invariance of this instrument across different sociodemographic groups and over time in a sample of primary care patients in Spain. Data came from 836 primary care patien...

The Physical Self-Perception Profile (PSPP) is widely used to measure self-evaluations in the physical domain and its validity has been supported in a wide range of samples. The purpose of this research was to examine the factor structure of PSPP and its factorial invariance across gender. Participants were 315 (131 males, 184 females) college students. Exploratory factor analyses showed that P...

Let $mathfrak{L}$ be the Virasoro-like algebra and $mathfrak{g}$ itsderived algebra, respectively. We investigate the structure of the Lie triplederivation algebra of $mathfrak{L}$ and $mathfrak{g}$. We provethat they are both isomorphic to $mathfrak{L}$, which provides twoexamples of invariance under triple derivation.

Accurate measurement of behavioral functioning is a cornerstone of research on disparities in child development. This study used the National Longitudinal Survey of Youth 1979 (NLSY79) data to test measurement invariance of the Behavior Problem Index (BPI) during middle childhood across three ethnic groups. Using the internalizing and externalizing behavior problem division derived by Parcel an...
